Description

BACKGROUND OF THE INVENTION

This invention relates to athletic type training devices and in particular, to training devices and methods useful for the martial arts, boxing, wrestling and physical fitness in general. More particularly, this invention relates to training devices useful for developing skill in the martial arts and boxing by providing simulated arms and legs for practicing various martial arts and boxing techniques.

Martial arts and boxing training involves, among other things, developing the ability to effectively strike an opponent and at the same time to be aware of and respond to strikes or attempted strikes by the opponent. When practicing martial arts or boxing with a live opponent blows often must be performed at partial speed or pulled to prevent injury to the opponent, as full contact with a live opponent may result in injury. The potential of injury to or from a live opponent exists even though each party attempts to moderate or simulate blows.

It is therefore common practice in martial arts and boxing training to practice blows without the benefit of an opponent. A disadvantage of practicing with no opponent is that it is extremely difficult to simulate the presence of an opponent, especially the bobbing and weaving and other realistic movements an opponent is likely to make. Therefore, a need exists for some means to permit a follower of the martial arts or boxing to practice with a simulated opponent. Such a simulated opponent would have specific advantages over the usual method of practice, without an opponent, which approximates shadow boxing.

Numerous martial arts or boxing hitting devices used to train students in the proper method of striking an opponent are known. Such striking devices include punching bags, striking bag platforms, simulated leg kicking devices, and other hitting surfaces. While many of these hitting devices operate reasonably well and generally achieve their objectives under the limited range of operating conditions for which they were designed, such devices have several disadvantages which make them less than optimal training devices. These devices often tend to be bulky, expensive, complicated, or ineffective. Oftentimes, the assistance of another person is required to stabilize and hold the target. This requirement not only increases the difficulty in scheduling workout sessions, but also exposes the person holding the device to injury. Also, many of these devices will not reset or restore to their original condition after each hit, nor are they adjustable to accommodate a wide range of hitting heights. Perhaps most important, these devices do not simulate human movements, such as ducking, hitting, feinting and the like. Consequently, a need exists for a training device and method which is participant-operated, safe to use, portable and realistic in its movements.

The subject invention overcomes the above limitations and others, and teaches a martial arts, boxing and physical fitness training device which provides simulated arms and legs for practicing various martial arts techniques and which is participant-operated, safe to use, portable and realistic in its simulation of human movement.

SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a martial arts training device which provides simulated arms and legs for practicing martial arts techniques.

Further in accordance with the present invention, there is provided a martial arts training device which is participant-operated, safe to use, portable and realistic in its movements.

Still further in accordance with the present invention, there is provided a martial arts training device, wherein the training device comprises:

an elongated tubular member having a first and second distal portions, wherein the tubular member has a first arcuate bend adapted to matingly engage an exterior of an associated, generally cylindrical heavy bag so as to engage at least a portion of the bag along a circumference thereof;

an elongated elastomeric member having opposed ends fixed to the tubular member on opposite sides of the first arcuate bend so as to define an aperture therewith, whereby the elastomeric member is adapted to secure the tubular member about the bag by securing the bag via friction to the first arcuate bend; and

a resilient cover disposed about at least a portion of the elongated tubular member.

Still further in accordance with the present invention, there is provided a martial arts training method, wherein the method comprising:

selectively contacting a resilient cover of an elongated tubular member having first and second distal portions, wherein the tubular member has a first arcuate bend matingly engaged to an exterior of an associated, generally cylindrical heavy bag so as to engage at least a portion of the bag along a circumference thereof, and wherein the tubular member has an elongated elastomeric member having opposed ends fixed to the tubular member on opposite sides of the first arcuate bend so as to define an aperture therewith, whereby the elastomeric member secures the tubular member about the bag by securing the bag via friction to the first arcuate bend so as to minimize relative movement between the bag and the tubular member upon such contact.

One advantage of the present invention is that it provides those training in the martial arts, boxing, or wrestling simulated arms and legs with which to sharpen kicking and punching skills and increases the quality of their training.

A further advantage of the present invention is that the invention is participant-operated allowing the participant to train without the assistance of another person.
